DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings wherein like numerals refer to like parts throughout, attention is directed first to FIGS. 1, 3 and 4 which are to be considered together. Reference numeral 10 designates a rigid, flat, generally rectangular metal vehicle frame which is secured to a carriage including an axle 1 1 and a spring suspension assembly 12 (FIG. 4). A pair of wheels 13 are mounted on the axle 11. The carriage including the wheels 13 are located substantially midway of the frame 10 for providing balance; however, when desirable, additional pairs of wheels may be included and rearranged to fit the specific needs of the user. Therefore, .it should be pointed out at the outset of this specification that the present configuration is disclosed for purposes of explanation only and is not meant to be considered in a limiting sense.

On the forward portion of the frame 10 a trailer hitch 14 is attached to two metal bar members 16 and 18 which diverge away from the hitch l4 and attach to the forward crossbar member, not shown, of the frame 10. On the forward portion of the frame 10 just behind the trailer hitch 14 is mounted a gas tank 20 resting on mounting blocks 22 which are secured to the frame. The gas tank 20 is adapted to contain a relatively large volume of burner fuel, such as propane gas and includes fittings, not shown, which are adapted to be protected by the metal shield 21. The fuel gas is utilized for powering a plurality of gas burners, two of which are shown in FIG. 1 and having reference numerals 24 and 26. The burners 24 and 26 are fed from a gas line 28 coupled to the tank 20 through a manually operated cut-off valve 30. Each of the burners moreover includes manually adjustable burner controls 32 and 34, respectively, for controlling the amount of fuel fed from each of the burners from the line 28 by means of flexible line couplings 36 and 38.

Two cylindrical broiler type grills generally designated by reference numerals 40 and 42 are mounted in tandem on a housing secured to the frame 10. The housing includes a front wall 44 and a rear wall 45 and the front wall 44 is located along the edge of one side of the frame behind the tank 20. The grills 40 and 42 extend inwardly for substantially one-half of the frames width. Each of the. grills 40 and 42 includes hinged lids 46 and 48, respectively, which have a curvilinear surface adapted to close on a common curvilinear body wall 50 which rests on and is secured to the walls 44 and 45. The lids when closed and body wall define a substantially circular cross section. Below the body wall 50 f the two grills 40 and 42 is located a respective fire box drawer 52 and 54 which rest on the frame above the burners 24 and 26. The drawers 52 and 54 additionally coact with the front housing wall 44 to provide a closed area when fully inserted therein, as shown. Each of the drawers 52 and 54 is provided with handles 56 and 58 to facilitate removal.

Just behind the rear grill apparatus 42 on the same side of the frame 10 is located a first beverage dispenser 60 which is adapted to include a burner, not shown, coupled to fuel line 28. The dispenser 60 is adapted to prepare either hot or cold beverages and includes three compartments 62, 64 and 66 which have independent spigot attachments 68, 70 and 72 coupled thereto for selective operation. FIGS. 1, 3 and 4 additionally disclose four upright bracket assemblies 74, 76, 78 and 80, each of which includes a horizontal bar member and which are secured to the frame 10 and the housing 44 fore and aft on either side to provide an attachment means and support for a serving table 82, 84, 86 and 88, respectively (FIG. 3). When desirable, just one of the tables may be utilized in any corner desired. The same may be said for two or three tables. Turning now briefly to FIG. 4, there is shown the serving table 86 coupled to the bracket 78 while table 88 on the other side of the trailer is being moved downwardly to couple to the bracket 80. Table 88 also discloses a pair of curved finger elements 90 which attach to the upper horizontal bar member. This configuration also pertains to the other tables 82, 84 and 86, as shown in FIG. 3.

Referring now to FIGS. 2, 3 and 4, in combination on the opposite side of the lengthwise portion of the frame 10 are located three deep fry compartments92, 94 and 96 contiguously mounted in tandem in a second housing which includes a common front wall 98 and a common rear wall 99, both of which are secured to the frame 10. Beneath each of the compartments 92, 94 and 96 is located a respective gas burner 100, 102 and 104 which rest on the frame 10 inside of the housing behind the front wall 98. The burners 100, 102 and 104 are slidablymounted by means, not shown, so that they may be selectively removed from the housing when desirable. Each of the burners is supplied fuel from the propane gas tank 20 by means of the fuel line 106 and respective flexible line couplings 108, 110 and 112. Each of the burnersalso includes separate burner controls 114, 116 and 118. Additionally, each of the deep fry compartments has its own drain and valve assemblies 120, 122 and 124 which are adapted to feed off the liquid contents and residue of the compartments exteriorly from the frontwall 98. The combination of the compartments 92, 94 and 96 with the housing 98 define a generally rectangular box-like configuration. Additionally, each compartment includes a generally flat lid 126, 128 and 130 which is hinged on the upper located a cauldron-type beverage dispenser 132 which is mounted on upright support members 134 and 136 as shown in FIG. 4. The dispenser 132 thus is located on the rear portion of the trailer frame 10 beside the other dispenser60. The dispenser132 additionally includes two spigots 138 and 140. When desirable, the contents of the dispenser 132 can be fed into the dispenser 60 by means of suitable hose and coupling means, not shown.

Directing attention now more particularly, to the structural details of the broiler grill and deep fry apparatusv thus described, reference is made now to FIG. 5 which is a cross section of the embodiment as shown in FIG. 1 and taken along the lines 5-5. FIG. 5 discloses a generally rectangular cross section of the deep fry compartment 92. The forward and rearward side portions thereof are part of the walls 98 and 99 and the hinged lid 126 is shown in a raised position. The bottom of the compartment 92 constitutes a relatively flat member 142 secured to the inner portion of the walls 98 and 99 substantially in the middle thereof. The deep fry compartment 92 thus constructed is adapted to contain any suitable deep frying material e.g., cooking oil, shortening, or deep frying fat, which can be heated to a liquified state and maintained at a predetermined temperature by means of the burner 104.

Regarding the grill portion, FIG. 5 illustrates a cross section of the grill 40. 'It discloses, among other things, that the cylindrical body wall 50 is supported by the vertical forward and rear housing walls 44 and 45. The hinged lid 46 is attached to the upper portion of the body wall 50 by means of a plurality of hinges 148 and its curvilinear surface also constitutes a circular cross section such that when the lid is in a lowered or closed position, the lid 46 and the body wall 50 define a closed cylindrical inner wall surface 144, the purpose of which is to provide an even distribution of heat throughout the interior of the grill. Ametal cooking grid 150- is mounted substantially horizontally at the mid-point of the inner wall surface 144 by means of flanges 152 and 154. It should also be pointed out that the end walls 156 of the lid 46 constitute a circular section which meet the end walls 158 of the grill housing which also constitute a circular section completing a full circle when touching. The two meet along an inclined surface 160. The lid 46, when raised, is adapted to be held in an open position by means of a pair of hinged support members 162 and 164.

Considering now FIG. 5 together with FIG. 6, in the lower portion of the grill body 50 a cut-out 166 is included whereby heat generated either by the burner 24 or charcoal and the like burnt in the fire box drawer 52 can enter into the grill assembly below the metal cooking grid 150. The cut-out 166 is not coextensive with the length of the grill body wall 50 but is only of a predetermined length greater than the width of the fire box drawer 52, as shown in FIG. 6. The reason for this arrangement is to prevent any undue amount of heat from collecting between the housing walls 44 and 45 below the body wall 50. Additionally, a relatively flat preferably metal heat deflector member 168 having a width less than the width of the fire box drawer 52 is located in a substantially horizontal position across the cut-out 166 so that it is directly in the path of the heat rising from the fire box drawer 52. The heat deflector 168 is shown in FIGS. 5 and 6 to be located approximately midway between the grid 150 and the lowermost portion of the grill body wall 50. Not only does the heatdeflector 168 serve to distribute the heat entering into the grill body but also prevents dripping grease or burning fat from any meat being cooked on the grid 150 from entering into the fire box drawer 52 to any great degree which would cause a flare-up which is a common hazard and inconvenience in cooking with this and all other types of charcoal grill apparatus.

Next, the configuration of the fire box drawer 52 should be considered for its unique configuration. The bottom surface 170 as shown in FIG. 7 contains a circular opening 172 which is adapted to be in registration with the burner 24 mounted under the frame 10 when the drawer is fully inserted into the housing wall 44 beneath the grill body 50 and its cut-out 166. A semicylindrical metal shelf 174 is positioned over the opening.l72 and raised a predetermined amount therefrom by'means of a second semi-cylindrical support member 176 and a rear support 178. The shelf l74'is-positioned in a substantially horizontal attitude whereas the support 176 is substantially vertical. The purpose of the shelf 174 and its forward support 176 is to hold a piece of wood such as a hickory log, not shown, while the remainder of the drawer 52 may contain charcoal. It should be pointed out the fire box drawer 52 can be operated with either the wood alone or the charcoal alone, or both depending upon the use intended. It should also be pointed out that when desirable the drawer 52 can be either entirely removed or can remain empty when inserted for operating the burner 24 by itself for purposes of simply providing oven-type heat. When wood or charcoal or the like is placed in the drawer 52, the burner 24 is utilized only for igniting the contents and thereafter turned off. It can be seen, therefore, that the present embodiment provides great versatility in its use.

What hasbeen shown and described, therefore, is a very versatile mobile kitchen which is adapted particularly for field use and the like where relatively large amounts of food and beverages can be prepared quickly and easily, such as at an outdoor barbecue and/or fish fry, and where the broiling of meats or the like is carried out on one side of the trailer and deep frying is carried out on the other side of the trailer. Portable tables are adapted to be attached to both sides of the trailer on either side thereof providing flexibility of service and both hot and cold beverages can be prepared and served from the rear of the trailer. While a mobile configuration is shown to be the preferred embodiment of the subject invention, it should also be pointed out that when desirable each of the components, particularly the grill assembly, can be utilized separately and in fixed or portable environments at the option of the user.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or scope of the subjoined claims.
